Hampden Park Signal Box, Hampden Park, Sussex.
Hampden Park signal box on the ex-LBSCR line from Lewes to Eastbourne. This signal box was built in the 1888. When I originally started watching trains in 1956, this box was fitted with a large wheel to manually operate the level crossing gates which have since been replaced with half barriers. 
The photo was taken from a Gatwick Airport-Eastbourne train on Saturday June 5, 1999.
